This presentation by JuliaKarpin and Anna Dorfman (F5 Networks) was delivered at VB2017 in Madrid, Spain.
A significant part of the malware research process is dedicated to reversing cryptographic algorithms in order to extract the decrypted content. Revealing this content provides access to the heart of the malware: all the strings, Windows API calls, DGA algorithms, communication protocols, and when focusing on financial malware, the list of targeted institutions and webinjects. Malware authors know that we're after this data, which is why they put considerable effort into constantly changing their encryption routines and designing customized implementation algorithms. Even the smallest change requires significant work on the part of the malware researcher: reversing has to be applied to reconstruct the encryption scheme.
Over the years, numerous plug-ins and tools have been developed to solve this problem. Some have been highly academic endeavours that relied on complicated algorithms to identify cryptography, but which were not adapted for real-world usage; others relied on signature checks to locate specific algorithms. We wanted to find a lightweight and practical implementation that would effectively speed up the research process. That’s why we developed an automated approach, based on a heuristic way of detecting such cryptographic algorithms regardless of the type of algorithm used, that extracts their plain text output. The implementation of this approach saves a lot of valuable research time.
Our implementation, "Crypton", works by unpacking the malware, then following injected code and memory allocations in order to identify blocks of cryptographic code, and inspecting the allocations for decrypted data. Our tool will follow all the processes created and injected by the malware as the decryption may happen in any one of them - therefore we must follow any execution flow.
We plan to give some insights into our work with the latest financial malware, their internals and their usage of cryptographic algorithms, compression routines and pseudo random generators. We will describe the idea and the architecture of the Crypton tool and present a demo with live malware and our complementary IDA-python script that identifies all crypto blocks inside a memory dump.

Mitosome

A mitosome is an organelle found in some unicellular eukaryotic organisms. The mitosome has only recently been found and named, and its function has not yet been well characterized. It was termed a 'crypton' by one group, but that name is no longer in use.

Mitosomes are almost certainly derived from mitochondria. Like mitochondria, they have a double membrane and most proteins are delivered to them by a targeting sequence of amino acids. The targeting sequence is similar to that used for mitochondria and true mitochondrial presequences will deliver proteins to mitosomes. A number of proteins associated with mitosomes have been shown to be closely related to those of mitochondria or hydrogenosomes (which are also degenerate mitochondria).

The CRYPTON algorithm processes blocks of 128 bits in the form of 4×4 byte arrays. The round transformation consists of four steps: byte-wise substitution, column-wise bit permutation, column-to-row transposition and finally key addition. CRYPTON uses 12 rounds of this encryption process. Due to the algorithm's nature, the decryption process can be made identical to the encryption process using a different key.

An algorithm is an effective method that can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input.

In relation to logic-based and artificial neural network-based clinical decision support system, which are also computer applications to the medical decision making field, algorithms are less complex in architecture, data structure and user interface. Medical algorithms are not necessarily implemented using digital computers. In fact, many of them can be represented on paper, in the form of diagrams, nomographs, etc.

In cryptography, impossible differential cryptanalysis is a form of differential cryptanalysis for block ciphers. While ordinary differential cryptanalysis tracks differences that propagate through the cipher with greater than expected probability, impossible differential cryptanalysis exploits differences that are impossible (having probability 0) at some intermediate state of the cipher algorithm.
Lars Knudsen appears to be the first to use a form of this attack, in the 1998 paper where he introduced his AES candidate, DEAL. The first presentation to attract the attention of the cryptographic community was later the same year at the rump session of CRYPTO '98, in which Eli Biham, Alex Biryukov, and Adi Shamir introduced the name "impossible differential" and used the technique to break 4.5 out of 8.5 rounds of IDEA and 31 out of 32 rounds of the NSA-designed cipher Skipjack. This development led cryptographer Bruce Schneier to speculate that the NSA had no previous knowledge of impossible differential cryptanalysis. The technique has since been applied to many other ciphers: Khufu and Khafre, E2, variants of Serpent, MARS, Twofish, Rijndael, CRYPTON, Zodiac, Hierocrypt-3, TEA, XTEA, Mini-AES, ARIA, Camellia, and SHACAL-2.
Biham, Biryukov and Shamir also presented a relatively efficient specialized method for finding impossible differentials that they called a miss-in-the-middle attack. This consists of finding "two events with probability one, whose conditions cannot be met together."

In cryptography, impossible differential cryptanalysis is a form of differential cryptanalysis for block ciphers. While ordinary differential cryptanalysis tracks differences that propagate through the cipher with greater than expected probability, impossible differential cryptanalysis exploits differences that are impossible (having probability 0) at some intermediate state of the cipher algorithm.
Lars Knudsen appears to be the first to use a form of this attack, in the 1998 paper where he introduced his AES candidate, DEAL. The first presentation to attract the attention of the cryptographic community was later the same year at the rump session of CRYPTO '98, in which Eli Biham, Alex Biryukov, and Adi Shamir introduced the name "impossible differential" and used the technique to break 4.5 out of 8.5 rounds of IDEA and 31 out of 32 rounds of the NSA-designed cipher Skipjack. This development led cryptographer Bruce Schneier to speculate that the NSA had no previous knowledge of impossible differential cryptanalysis. The technique has since been applied to many other ciphers: Khufu and Khafre, E2, variants of Serpent, MARS, Twofish, Rijndael, CRYPTON, Zodiac, Hierocrypt-3, TEA, XTEA, Mini-AES, ARIA, Camellia, and SHACAL-2.
Biham, Biryukov and Shamir also presented a relatively efficient specialized method for finding impossible differentials that they called a miss-in-the-middle attack. This consists of finding "two events with probability one, whose conditions cannot be met together."

Crypton - exposing malware's deepest secrets

This presentation by JuliaKarpin and Anna Dorfman (F5 Networks) was delivered at VB2017 in Madrid, Spain.
A significant part of the malware research process is dedicated to reversing cryptographic algorithms in order to extract the decrypted content. Revealing this content provides access to the heart of the malware: all the strings, Windows API calls, DGA algorithms, communication protocols, and when focusing on financial malware, the list of targeted institutions and webinjects. Malware authors know that we're after this data, which is why they put considerable effort into constantly changing their encryption routines and designing customized implementation algorithms. Even the smallest change requires significant work on the part of the malware researcher: reversing has to be applied to reconstruct the encryption scheme.
Over the years, numerous plug-ins and tools have been developed to solve this problem. Some have been highly academic endeavours that relied on complicated algorithms to identify cryptography, but which were not adapted for real-world usage; others relied on signature checks to locate specific algorithms. We wanted to find a lightweight and practical implementation that would effectively speed up the research process. That’s why we developed an automated approach, based on a heuristic way of detecting such cryptographic algorithms regardless of the type of algorithm used, that extracts their plain text output. The implementation of this approach saves a lot of valuable research time.
Our implementation, "Crypton", works by unpacking the malware, then following injected code and memory allocations in order to identify blocks of cryptographic code, and inspecting the allocations for decrypted data. Our tool will follow all the processes created and injected by the malware as the decryption may happen in any one of them - therefore we must follow any execution flow.
We plan to give some insights into our work with the latest financial malware, their internals and their usage of cryptographic algorithms, compression routines and pseudo random generators. We will describe the idea and the architecture of the Crypton tool and present a demo with live malware and our complementary IDA-python script that identifies all crypto blocks inside a memory dump.

Bitcointalk thread: https://bitcointalk.org/index.php?topic=1638450.0

The challenge to implement an appropriate data processing pipeline to make good use of your indicators of compromise has been successfully addressed over the last few years. Even with all
the push for automation and orchestration, a fundamental question remains: which data should you be ingesting in your detection pipelines? There is no lack of data available, shared or not,
paid or not. But how do you keep your cyber threat intelligence (CTI) incident response team from spinning its wheels on a pile of CTI mud? This presentation will discuss statistical analysis
you can undertake using the CTI indicators that you collect and your own network telemetry.

What is a zero-knowledge proof?

One of the more elegant and counterintuitive ideas in modern cryptography is the notion of a zero-knowledge proof (ZNP). A ZNP allows one party (the prover) to prove to another (the verifier) that they know a secret without revealing any information about the secret itself.It’s a totally wild idea that has deep implications for online security.
